# How Akka maps to EAI Patterns

Might be up for debate or just plain wrong. Just some notes I scribbled down some time ago. 

-----------------------------------------------------------------------------------------------------------------
EAI PATTERN                     AKKA PATTERN                  REFERENCE
-----------------------------------------------------------------------------------------------------------------
Point to Point Channel          Regular Actor Communication   http://www.eaipatterns.com/PointToPointChannel.html
Event-Driven Consumer           Regular Actor Receive         http://www.eaipatterns.com/EventDrivenConsumer.html
Message Selector                Actor with Stash              http://www.eaipatterns.com/MessageSelector.html

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

This is a simple shell script that is designed to provision both nginx and node on your machine. I primarily wrote it for use with Vagrant and an example Vagrantfile is included in the Gist as well.

Brightess Fix

When brightness controls stop responding manually trigger a brightness update. Once this is done brightness controls seem to respond again. Not sure if the lspci command is required, when my linux foo is stronger I'm sure I'll know...

lspci -nn | grep VGA
echo 3500 | sudo tee /sys/class/backlight/intel_backlight/brightness
